is this a joke !
from just joining sal to 5y later, you didn't think he improved over 10k ???
do you follow the sport ?
they were virtually identical times
in 1st he got decent drafting & was worth 3'28-low perfect race
in 2nd he got crap drafting, worth 3'27-flat if he got perfect race/drafting
he improved his intrinsic 1500 by nearly 1.5s in 2y
no
you didn't
very likely due to being in heavy training with no rest for race &/or illness
no
he was running 10k there not a mile
i go suggest you see what his last 1600 was in peking
no
you used a meaningless mile race as evidence of 10k shape
no
it wasn't
the peking stadium is a very enclosed stadium with very little wind at ground level
go fetch some wind readings for the day...
nonsense
it was 81F with 60% humidity
that humidity doesn't allow the sweat to evaporate to cool runner down, so slow build up of internal heat
if you don't think excess heat/humidity doesn't low a 10k, then you have no clue about the sport
